Because of the filming date, I'm predicting a visit to the Middle East/North Africa region. Maybe we'll finally see another Egypt leg, likely in a more politically temperate area like Hurghada, Luxor, Sharm el Sheikh, or Alexandria. I also think Oman is a plausible guess; we haven't seen a visit there in a while. The producers have already said Qatar isn't happening because something like "the government is disorganized". I don't think we'll see UAE or Morocco due to having seen it in 28 and 25, Lebanon is too close to Syria, Palestine/Israel is too controversial at a time that TAR desperately needs good ratings, so my guess is Oman, Egypt, Jordan, Bahrain, Jordan, and/or Tunisia. Tunisia and Jordan are the most likely because they are the most politically stable (especially Tunisia), plus Tunisia hasn't been seen since 1 and Jordan has never been seen.
